I adore Kozlik's Canadian Mustard. Not only are they the best reason to visit St.Lawrence Market, they make quality delicious mustard and have excellent customer service. This Christmas I packed some of their mustards into my gift baskets and everyone was pleased. I kept a smoky flavour one for myself. The Dijon by Anton and Horseradish are both particularly tasty as well..
